Vegetable oil refining is necessary for vegetable oils & fats so they can be used for cooking and frying foods. Usually there are two ways of refining vegetable oil, they are Physical Refining & Chemical Refining.

3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save enerLD by reducing the evaporation capacity.

5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.

6. Specially suitable for the extraction of various pre-pressed meals.

Dewaxing/winterising process are as follows:

The oil is cooled in crystallisers and gradually the crystal formation takes place. Here filter aid is also added.

The oil is then transferred to a maturator where the crystals are allowed to grow. The oil is continuously cooled by the help of glycol water flowing through the coils.

Finally the oil is filtered on hermetic pressure leaf filters to remove the waxes.

For Rice bran oil, LD has developed P P Filters which are more suitable for high wax oil.

The major advantages of this process is :

Single plant can be used for Dewaxing and Winterising.

Optimum care is taken to maintain the formed crystals till filtration.
